The research team prepared its guidance based on a literature review, an extensive survey of nearly 50 airports, and case studies of 12 airports. The guidebook begins with an overview of regulatory requirements as they relate to LED airfield lighting and a summary of the survey and case studies. The report then provides guidance on maintenance, including acceptance testing and warranty, fixture obsolescence and spare part recommendations, preventive maintenance and refurbishment/repair, maintenance practices during pavement repair, and environmental factors (e.g., vibration and moisture). The guidebook also covers operational considerations, including circuit configuration, heaters, monitoring, photometric and chromaticity analysis, and return-on-investment. The guidebook is supplemented by sample system requirements and maintenance schedules. The guidebook will be of particular interest to airport operations and maintenance (O & M) practitioners seeking to maximize the potential O & M benefits that LED lighting offers as they integrate and/or replace older airfield lighting with this new technology.  aIncludes bibliographical references (page 62) 0aRunways (Aeronautics)xLighting 0aLED lighting 0aLighting 0aLight emitting diodes1 aDennie, Chuck,ejt.auth.1 aElshetwy, Shady,ejt. auth.1 aLean, Doron,ejt. auth.1 aVigilante, Joe,ejt.auth.2 aNational Research Council (U.S.).bTransportation Research Board2 aAirport Cooperative Research Program1 aUnited States.bFederal Aviation Administration 0aACRP report ;v148.x1935-9187403Download: Knoveluhttp://app.knovel.com/hotlink/toc/id:kpLEDALSO1/led-airfield-lighting?kpromoter=marc  a.b12292771bmngc cn  a251209  b0c190207deeh  fng0  c69072d69072
